My baby boy sleeps well at night, often goes 7-7 with a dreamfeed. However daytime naps are a battle. We put him down in his cot and he goes down for 30 mins before waking up, clearly grumpy and wanting more sleep! He will sleep in the car/pram for longer than 30 mins not a problem and sleeps on me for longer than 30 mins! Anyone had this or any tips on how to make him sleep longer?
